IPC: H05B3/00
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To reduce standby time and power consumption required till attaining set temperature and to hardly cause an ignition phenomenon even in a state where paper or the like comes in contact with the surface of a fixing roller at the time of runaway by making an electric heating sheet intervene between the core body and the surface coating layer of the fixing roller. SOLUTION: The fixing roller 1 is constituted by making the electric heating sheet 6 intervene between the mandrel 4 consisting of iron or aluminum and the surface coating layer 5 consisting of rubber or resin excellent in releasing property. The sheet 6 is provided with cylindrical electrodes 7 and 8 on both end sides, and electrode arms 10 and 11 slide in contact with the electrodes 7 and 8. In such constitution, voltage is applied to the sheet 6 from the outside through the arms 10 and 11 and the electrodes 7 and 8. The voltage is always applied to the sheet 6 and the surface temperature of the roller 1 is detected by a temperature sensor.  When the surface temperature of the roller 1 attains the set temperature the application of the voltage to the sheet 6 is temporarily stopped and when it is lower than the set temperature, the voltage is applied so as to keep the surface temperature of the roller 1 nearly constant.

Abstract: PURPOSE:To make mechanical interlocking at a narrow space performable as well as to detect the accurate residual quantity of cut paper, by making lifting motion of a paper feeding table interlock with a rheostat in use of attraction of a magnet, and making a variation in the resistance value so as to be displayed on a display part. CONSTITUTION:When a paper feeding table 2 goes up, the L-shaped metal fitting 25 clamped to this paper feeding table 2 goes up as well while pushing up a lever 24 of the rheostat 23. When the paper feeding table 2 goes down, this lever 24 of the rheostat 23 is made to go down up to the lower limit of its movable range by dint of magnetic suction force. And, when the paper feeding table 2 goes down yet more than the movable range lower limit, the L- shaped metal fitting 25 is separated from the magnet 26, and the paper feeding table 2 only goes down. A resistance value variation in the rheostat 23 to be produced by this lifting motion is displayed on a display part, thereby detecting the residual quantity of cut paper. Thus, mechanical interlocking at a narrow space is made performable and, what is more, the accurate residual quantity of the cut paper is detectable.
